Objective Ascending thoracic aortic aneurysms carry a risk of acute type A dissection.
Elective repair guidelines are designed around size thresholds, but the 1-dimensional …

Background In ascending thoracic aortic aneurysm risk stratification, aortic area/height ratio
is a reasonable alternative to maximum diameter. Biomechanically, aortic dissection may be …

Objective Guidelines for repair of bicuspid aortic valve–associated ascending thoracic aortic
aneurysms have been changing, most recently to the same criteria as tricuspid aortic valve …

The stress distribution in ascending thoracic aortic aneurysms is determined by the
mechanical properties, geometry, loading conditions, and zero-stress state of the …

Background Bicuspid aortic valve–associated ascending thoracic aortic aneurysms (BAV-
aTAAs) carry a risk of acute type A dissection. Biomechanically, dissection may occur when …

Risk of aortic dissection in ascending thoracic aortic aneurysms is not sufficiently captured
by size-based metrics. From a biomechanical perspective, dissection may be initiated when …

Objective Current guidelines for elective surgery of ascending thoracic aortic aneurysms
(aTAAs) use aneurysm size as primary determinant for risk stratification of adverse events …

Objectives Rupture and dissection are feared complications of ascending thoracic aortic
aneurysms caused by mechanical failure of the wall. The current method of using the aortic …

The development of an ascending thoracic aortic aneurysm is likely caused by excessive
hemodynamic loads exerted on the aneurysmal wall. Computational fluid-dynamic analyses …

The aortic dissection (AoD) of an ascending thoracic aortic aneurysm (ATAA) initiates when
the hemodynamic loads exerted on the aneurysmal wall overcome the adhesive forces …
